Definitions

  • the present invention relates to a furnace for reheating, maintaining, and accumulating steel products.
  • Flat products and long products processed in hot rolling mills to form sheets, strips, beams, bars, etc ... are more and more frequently made from liquid steel contained in a pocket and poured continuously in a mold followed by rollers which make it possible to extract the form obtained by controlled cooling of the steel just sufficient to pass from the liquid metal form to the solid form, the semi-product obtained thus at the end of continuous casting is in generally at a temperature above 1000 ° C.
  • rolling it as soon as it leaves the casting represents a substantial energy saving compared to the conventional process which consists of storing semi-finished products before heating them to 1250 ° C for ability to laminate them.
  • patent EP 0 370 916 B1 describes a reheating, holding and accumulation furnace which comprises two groups of support beams and transport beams which can both move in the vertical direction and lie in lower planes, identical or greater than the reference plane given by the rollers which make it possible to load and unload steel products and, in combining the respective planes of the support beams and the transport beams, in order to move or not move the products which are on each of the groups of support beams.
  • the movement from the charging to the charging is controlled so as either to accumulate the steel products in the first zone defined by the first group of support beams or to make them cross this zone as quickly as possible to feed the rolling mill and create an available space in the oven to store there possibly products from continuous casting in case of shutdown of the rolling mill.
  • the drawback of the installations described in the prior art lies in the limitation of the transfer speed which cannot be equal to or less than the cycle time and the possible travel of the transport beams.
  • These transport beams follow a rectangular cycle with a total duration of the order of 40 seconds or more, comprising a first ascent phase which makes it possible to release the support beams, a second horizontal transport phase then a third deposition phase products which have thus progressed by one step on the support beams before the fourth phase of returning back to the initial position; we see that during phases one, three and four the products do not move, so only a quarter of the cycle is active in terms of product progression inside the oven and also the step or translation in the horizontal plane of the transport beams is generally limited to less than 0.6 m due to the necessary combination of vertical and horizontal mechanical movements.
  • This limitation can constitute a serious handicap both in terms of the production capacity of the furnace and its capacity to free up in the oven sufficient space to store products from casting if the shutdown of the rolling mill turns out to be longer than expected. or that usual.
  • the slow speed of transfer of the products through the storage area a speed which represents an advantage when the products in the oven are practically cold, is a drawback when the semi-products arrive directly from the continuous casting since it requires maintaining this zone at a high temperature to avoid cooling of the products before entering the reheating zone.
  • This high temperature maintenance is a handicap both in terms of energy and the environment because in normal times the products from continuous casting must reach the heating or even homogenization zone as quickly as possible and consequently the zone storage is empty.
  • the present invention proposes to overcome these drawbacks by providing a satisfactory response both to the problem of speed of transfer of the products and to that of keeping the storage area at high temperature by making it possible to take advantage of the fourth return phase. behind the transport beams to advance the products in the oven as will be seen in the device which follows. To the possibility of reheating cold products is added that of being able, during operation, to adapt the residence time of semi-finished products depending on their temperature in the oven.
  • the furnace for storing, reheating and maintaining steel products in which the products circulate according to a displacement path on longitudinal members placed so as to connect in the transverse direction a charging area and a charging area, the heating and holding zones comprising, on the one hand, product support beams and transport beams placed at a certain distance from said support beams and capable of carrying out a lifting movement relative thereto and a movement of movement horizontal advancing the product step by step, characterized in that said storage zone further comprises support and transport beams of the type described above, at least one group of mobile support beams, independent of the oven bottom , which can move in a horizontal reciprocating translational movement which is carried out during the return phase of the transport beams.
  • the oven object of the present invention comprises two or more storage, heating and holding zones.
  • the furnace comprises a so-called storage zone which in normal times must remain available to receive the casting products in the event of the rolling mill stopping, a reheating zone, and a homogenization zone before discharging.
  • the reheating and homogenization zones are designed like the usual reheating ovens comprising transport beams 2 said mobile or support beams 1 said fixed, the four-phase cycle described in the prior art allows the mobile beams 2 to transport products by one step per cycle from the entry of the reheating zone to the discharge at speeds generally varying from 0.9 m / min to 0.3 m / min or less.
  • the storage zone comprises transport beams 2 integral with a structure 4 such as those produced in the heating and homogenization zones and one or two groups of support beams 1 which, unlike a conventional oven, are not integral with the fixed base 3 of the furnace or as described in the previously cited patent.
  • the oven object of the invention comprises a structure 5 comprising a plurality of support beams 1, independent of the hearth 3 of the oven and capable of a horizontal translational movement towards the front or rear.
  • These groups of support beams 1 subjected only to a horizontal translation can have a stroke of 1m or more depending on the supply requirements of the furnace, this horizontal movement takes place with the load during the phase four of return of the transport beams 2 , which makes it possible to move the products of the pitch of the support beams 1 linked to the structure 5, for example 1 m, this pitch adding to that of for example 0.6 m made thanks to phase two of the transport beams 2 linked to the structure 4.
  • the transport speed through the storage area is thus multiplied at least by 2.66 in this example reducing the residence time in the same proportions, under these conditions it becomes pointless to maintain the storage area at normal temperature at high temperature, we can be satisfied with keeping it at temperature by the fumes from the heating and homogenization areas going towards the conduits leading to the chimney of evacuation of the products of combustion of the furnace.
  • the product P has been loaded by means usual for reheating ovens at the inlet of the oven onto the group of support rails 1 which is in the rear position relative to the fixed support rails 6 of the following zones, the group of support beams 1 moves forward by a full pitch A (in the example 1 m) during ( Figure 2) the mobile transport beams 2 move in opposite directions under the load P, from the value of a step B (in the example 0.6 m).
  • the transport beams 2 move vertically upwards, freeing the groups of support beams 1 from their load of product P which now rests on the beams 2 which advance by a step B (0.6 m) while ( Figure 4) the groups of support beams 1 move back a step A (1 m) to return to their initial position.
  • the speed of movement of the products in the storage zone allows it to be empty in normal times, in the event of the rolling mill stopping, the system of support beam group 1 remains in a fixed position, the products are transported from the charging to the charging by the transport beams 2, the progression is one step B at each cycle, depending on the production required the cycles are linked (every 40 s in the example) to free a space in the oven intended for a product coming from continuous casting, or are separated by a stopping time which may be several minutes giving displacement speeds of the order of 0.3 m / min or less.
  • the speed of movement of the products must therefore be adjusted so that the '' we will obtain by increasing the downtime between two successive cycles and by varying the pitch A from 0 m to the maximum pitch A (1 m in the example) as well as the pitch of the transport beams from 0 m to B ( 0.6 in the example).
  • the present invention is not limited to the exemplary embodiments described and shown above, but that it encompasses all variants thereof.
  • it seems sufficient to equip a single zone with groups of support beams animated with horizontal translation movement it It may perfectly be conceivable, for reasons of flexibility or supply from several castings for example, that two or all of the zones of the furnace may comprise such groups of support beams.
